Рекомендации по сопутствующим товарам
How does fluorescence technology improve dissolved oxygen measurement compared to traditional membrane probes?
Fluorescence probes measure DO without consuming oxygen, avoiding polarization and electrolyte maintenance. This provides stable, fast, and accurate readings even under variable flow or aeration conditions, reducing downtime and operational cost.
What makes this meter suitable for both field and laboratory water quality applications?
The meter combines IP67 waterproof protection, lightweight design (420g), long probe cable, and portable form factor with automatic temperature, salinity, and air pressure compensation, ensuring consistent performance indoors or on-site.
How reliable is this instrument under different environmental conditions?
It supports -10–60°C operation, 10–85% RH, altitude compensation, and has built-in data storage & backlight display. These features allow engineers to obtain accurate, reproducible readings in challenging environments.
Can this meter store and manage data for regulatory compliance or long-term monitoring?
Yes. It includes manual data logging, USB interface for export, and optional GPS tagging. Engineers can track dissolved oxygen trends over time, supporting compliance and process optimization.
What maintenance requirements should a procurement manager consider?
Unlike membrane DO meters, fluorescence sensors require minimal maintenance, no electrolyte filling, no membrane replacement, and calibration is infrequent, significantly lowering long-term operational cost.
How does compensation for salinity, temperature, and air pressure enhance measurement accuracy?
Dissolved oxygen readings are sensitive to these factors. This meter provides automatic temperature compensation, manual salinity adjustment, and air pressure compensation (50–115 kPa), обеспечивая precise, reliable results across diverse water bodies.
